The several .parts referred to yare shown in Fi l. lilith thispreliminary description l shall now pro- '.ceed .tod 1' tie apparatuseinbodyingi` `in invention. The apparatus comprises two oppesite'ends ofaehine. with certain interconnections tterdescribed, and a descriptiono'gt one of `the units VWill therefore be suilicient.

'lliefraine for supporting such a. unit is preferably in the forni of aflat vertical Wall .litorined Withsuitable Suppoiting` legs 18. @n faside oi. the Wall 17, which lfshall `reter toasthe rear side, visible'inFigs. 1 and 1l, Ya spool 19, for the hiking ribbon 11, isV car- .ried one rotatable shaft .20, journalled in The spool 1,9 is slidable Vaxially:on the ,shaft 20, so aste permit the ,ready positioning thereon, theconnection 'bete/reen itlie saniebeingniade by ineens ot a .slot 21 finthe shaft 2O adapted .to receive pin '.22 fixed Within .the centralopening of the spool. As shown in Figs. 1 and 41, the roller l2 andthespool 19 arepositioned on the saine side of 'the Wall 17, the 4iornierbeing Ypositioned in a 'plane above the latter, and nearer the end ofthe traine, so that the ribbon 111 Aextends troni the `spool toward the@adjacent end of vthe machine 'and upwardly over tlie roller 12 to theroller 12 attheop- :pos'te Vend ofthe machine. On the ,saine :side ofthe Wall 17 with the spool 19, an

Varni ,23 is secured on a shaft 24, journaled in the Wall 17. The arni23 is in the form oitfa fiat paddle, as best shown in Fig. 1, andvextends .between theends 24J, 25, of the' spool 19. The arm 23 issecured to the shaft by means of an arin 26 iixed on the shaft 24.

"The arm 26 is provided with screw 27 adapted to engage a lug 28 on thearin 23 :shafts .and 2d erin .23 isin the position shown in Fic'andtheleyer is in 'the postion shown Aallies. Gila-rid 8, .andrrlien thespool is Wound Which is loosely mounted on rthe shaft 211. Thus, bymeans of the screw 27, the position of thel arm 28 may be adj usted asdesired on the-shaft 21 and the sanie is secured in its adjustedposition by ine-.ins ot a screw 29 on the arin 23, which extends thru aslot 30 in the arin 26 in a manner readily understood. rl`he purpose. otthe arni 23 is twofold, lirst, it is urged against the ribbon 11, bymeans later described, and thus maintains a proper tension on thefibbon, and second, iccontrols the eedng and reversing' inechansni, asalso later described. ln order to remove the spool 1S) from itsshaft'20, the arm 23 is rotated clockwise, as viewed in F d, until it isclear or the sides 2l and 25 or the spool. For holding' the arm 23 inVits clear position, it is provided With a suitable shoulder 31 adaptedto be engaged by -aparrl2'and held in this iosition. .The both extendthrough the Wall V17 and project on its i'front side. As sinn-vn inFigs. (i to 9, the shaft 2/1 has lined on its end, on the trent si le ofWall 1'?, a, lever .33 formed with a xshoulder rlie lever 35 i'iormallyurged in a counterclocku'ise direction by a spring, 35 connected theretoat one end and connected atv its opposite end with a locking; piecepivoted on the shalt 20L, as besty Shown in F 8 land 9, pulling thesaine downwardly. it the saine time the shoulder 3l is urged ui uz yagainst a pin carried on an arm loosely pivoted at one end on the shaftrlhe opposite end ot the arm 3S extends loosely into a notch 39 of a trimember il() looselypivoted on a shaft l1 ...u the traine. lt will thusbe lseen that the sprin rotate the sli-a' cloc W The clockwise rota,-

Thus, the position ot the lug' 42 contrelled by the trigger ineinberL10. lli/hen the yspool is empty, the `arm 34C engages the pin 37,moving the trigger .arin 38 upwardly, thereby causing' the triggermember l0 to push the lug i2 forward against the action of the spring,in which position its notch e3 lOl) is in the line of travel of the padYarin14 and adapted to be engagedithereby when it is moved doivn by thecam 16, as shown in Fig. 8, and When the spool is `full, lthe parts areas shown in Fig. 9, in which posit-ion the notch 43 is free of and outof the line of `travel of t-he pad arm 14, as shown in Fig. 9. Theshat't 44, which supports the lug 42, is carried at one end of an armwhich is pivoted at its Opposite end to a member 46 secured to the frame17. The arm 4551s con- `iiected at'its shaft 44 by means of a link 47With a substantially vertical rod 48 Which extends loosely Ythrough alugI 49 .on the frame. The rod 48 is formed with a shoulder A50 and aspring 51 surrounds the rod and is interposed between the shoulder 50arm 14.

thereon and the lug 49, thus acting to maintain the lug 42 in its upperposition as shown in Fig. 9 and to return it to that position after ithas been moved down to its lower position, shown in Fig. 3, by the padThe link 47 is termed with an'y extension k52 formed with a slot 53.

The opposite end of the shat't 2O has fixed thereto on the front side ofthe Wall 17 a ratchet vvheel 54, best shown in Figs.6 and 7, adapted tobe rotated in a counter clockvviseA direction so as to Wind the ribbonon the spool. The ratchet wheel 54' isA driven by the pad arm 14. Asshown in F igs.` 1 to 3 the arm 14 has an arm 55 pivoted thereto on itsunderl side, to which is pivoted Lat right angles a pavvl 56,substantially U- shaped in cross-section so as to providesi-de walls 57and 58 thereon. LThe end: of theV pawl 56 is provided With-a suitabletooth 59 at its lower end adapted to enga-ge the teeth of the ratchetwheel 54, and ,a spring 60 is interposed between its upper` end and thearm 55 so as normally to urgethe tooth 59' into engagement with theratchet Wheel 54. A locking member 61, best shovvnin Figg5, is pivc-tedon the shaft 20, carrying a shoe 62 at one end arranged to cover some ofthe teeth ot' the ratchet Wheel 54, and provided witha raised portion 63on its periphery. The locking piece 61 is also provided with a pin 65which is positioned in the slot 53. 'A'

pawl 66 is pivoted on a shaft 67, adapted to engage the teeth of ratchetWheel 54. he paivl 66 is also providedwith a pin 63 adapt-- ed to engagethe periphery of locking piece 61. The lockingpiece 61 has tivopositions shown in Figs. 6 and 7 respectively, and is actuated by thepad arm 14 through lug 42.

Let it be assumed that the spool is empty y as shown in Fig. 1, andready to be Wound in Whichcase the parts are as shown in Figs. 6 and 6.In' this case, the arm23 is in its innermost position as shown in F ig.1.y andY the lever 33 is 1n its innermost position shown in Figs. 6 and8 in which the trigger member 40 acts against the lug 42, placing theynotch 43 'in line to be engaged by thepad arm when" it is moved downbythe cam 16. vAt this time the locking piece 61 is in the positionshown in Fig. 7, in which the shoe 62 prevents the patvlf56 tromengaging the ratchet Wheel 54.

1t must be rememberedthat the pad` arm 14 Vthe extension 52 ot' whichengages the pin 65 on the piece 61 and thus rotate rthe same about itsaxis 20. This operation continues until the spool is fully Wound, whenthe lever 33 is moved by the paddle arm 23 to the position shown in Fig.fi at which time, the trigger 40 releases the Vlug 42 and allows it tobe drawn free ot the spring 45. It is ot' course understood that whenthe spool at oneend ot the machine is' empty, 'the other is fu'll, thusvwhen the parte or' a spool at'one end ot the machine are as shown inFig. 7, the parts o1' the spool at the other end of the machine are asshown in Fig. f6.v 'The locking pieces 61 of the 'tivo 'units areconnected by means o1' a rod 70, thus when a spool is full as shown inFig. 7, the other spool is empty and its locking piece is.l thrown tothe position shown in` Fig. 6, which moves the locking piece ot the fullspoolto the. position shown in Fig: 7, in which case, the vshoe V62carried .thereby shields the teeth ot the ratchet wheel 54116111engagement by the pad arm paivl 56. The

sides 57 and 5S ot' thepaivl 56 now serif'e to f guider the pawl voverthe shoe 62. 1n this position ot the locking piece 61, thepin 68 restson the raised portion 63 of said piece and holds the paivl 66 free o1"the ratchet Wheel thus permitting the same to be rotated yin theopposite direct-ion as the spool is unwvound.

The pawl 66 is normally urged into engageby ment With the ratchet 54'bya spring 71 and prevents .the same from rotating in the oppo sitedirection While the spool associated therewith isV being Wound.Preferably the ends'pot the levers of the two units are connected by achain 72 soas'to aid each other in performing' `their 'functions Aspring 35 of considerable strength is desirkable since this serves toactnate the trigger member 46, to tensiontlie ribbon on its ciated spoolandto positively hold the ing piece 61 in either of `its tv n* It isobvious that as the spooi: is

diameter of the ribbon thereon increases,-

tliusplacing its associated spring 35-under greater tension and morderto prevent this tension from becomingl too great, the same isceunteracted by connecting theflevers 33 iio together, so that thespring of the other spool which is being unwound may exert a pullon theformer spring- 35.
